Silent and Comfortable
Market leader, this high-performance, optional sealed and pressurized cabin offers its driver a cleaner and quieter working environment, with excellent visibility of the working tool. Always striving to be a market reference, the D3 series also includes, as standard, a seat with controls adjustable by a manipulator for the comfort of its driver.
Optimal Performances
The high-performance powertrain group offers optimal efficiency and high production capacity thanks to its electronic torque management system, standard two-speed transmission, and electronic hand and foot accelerator, which can also serve as a deceleration pedal.
Simplify Your Work
The CAT® "smart leveling" system provides advanced technology, integration, and features such as automatic bidirectional leveling, return to the tool's digging angle, and tool position control."""
A Smooth Ride
The standard and fully independent torsion axle suspension, combined with the optional speed-controlled anti-sway system, improves the machine's performance on rough terrain, providing better load retention, increased productivity, and greater driving comfort.
Optimal Machine Capacity
Optimize the capacity and control of the machine thanks to the available advanced display, which allows adjustment from the screen of the equipment response, Hystat command response, and slow approach command. It also includes a multilingual functionality with customizable layouts, a security system, and a rear vision camera.
